Students will measure the pH of water using either pH paper or a pH meter.
Teachers Guide Supporting Protocols
Protocols to help in completion of the main protocol
Students will measure the alkalinity of water using an alkalinity test kit.
Students will measure electrical conductivity of water at freshwater hydrology sites.
Hydrosphere protocols introduction document.
Instructions are provided on how to select, describe and map a hydrosphere study site.
Students will first measure water transparency at their undisturbed study site using a transparency tube or Secchi disk.
Teachers Guide Field Guides
Step-by-step instructions for collection data according to the protocols.
Teachers Guide Data Sheets
Sheets to be filled out during data collection
Teacher Guide Learning Activities
Activities to help students learn more about the instruments and protocols
Introduction document to the Hydrosphere Investigation Area Learning Activities.
Students will make a 3-dimensional model of a catchment basin to understand how water moves through the basin and explore how water is affected when there are changes in the basin.
Students will model the changes in soil water storage over a year.
In the classroom, students practice using the instruments or kits for protocols, exploring the range of measurements and sources of variation and error.
Students will create mixtures of water samples, soil samples, plants and other natural materials to better understand the importance of pH levels.
Students will investigate how they use their senses for observation and why we use instruments to collect data.
Students become acquainted with their Hydrosphere Study Site.
